A study of 32,000 women found that those with an early chronotype, or sleep-wake preference, were significantly less likely to develop depression.
Scientists have identified a key enhancer of Sox9 -- a gene critical for male sex development -- and demonstrated that deleting this non-coding DNA results in male-to-female sex reversal.
Dr Guillaume Canaud at the Necker-Enfants Malades Hospital AP-HP, the Paris Descartes University, Inserm and his team recently demonstrated the efficacy of a novel medication in a cohort of 19 patients suffering from CLOVES Syndrome (Congenital Lipomatous Overgrowth, Vascular Malformation, Epidermal Naevi) or similar disorders. This study, published in the journal Nature, is an example of precision medicine and demonstrates the major benefits of this therapeutic strategy for these patients, who have seen their health and quality of life improve significantly.
Water is transported from the blood into the brain via an ion transporter, a new study on mice conducted at the University of Copenhagen reveals. If the mechanism can be targeted with medicine, it may prove relevant to all disorders involving increased intracranial pressure, including brain edema in connection with stroke as well as hydrocephalus, also called 'water in the head.'
Neuroscientists at EPFL have located the cells that help reprogram long-lasting memories of traumatic experiences towards safety, a first in neuroscience. The study is published in Science.
Five new species of eye-catching snakes with curious eating habits were found to inhabit forests in Ecuador. With four of them already deemed at risk of extinction, the international research team decided to auction their naming rights and use the money to purchase and save the previously unprotected plot of land where some of these species dwell. Their study is published in the open access journal ZooKeys.
Trachomatous trichiasis, caused by the bacterium Chlamydia trachomatis, is one of the leading causes of preventable blindness worldwide. It is common in areas of the world that lack access to health care and clean water. A relatively simple surgery can spare the patient's vision, and although this surgery is usually performed free of charge in endemic regions, multiple studies indicate that surgical refusal is common.
Spiders take flight on the smallest of breezes by first sensing the wind, and then spinning out dozens of nanoscale fibers up to seven meters long, according to a study publishing June 14 in the open-access journal PLOS Biology by Moonsung Cho, Ingo Rechenberg, Peter Neubauer, and Christoph Fahrenson at the Technische Universität in Berlin.
Female genital mutilation (FGM) increases the risk of developing mental illness and changes the body's reactions to stress.
Sharks are often the subject of TV specials or news stories focusing on their attacks on humans. But scientists are finding that sharks could inspire a new type of surface that would attack bacteria, helping humans instead of hurting them. As reported in ACS Applied Materials & Interfaces, researchers have designed a coating that is infused with antimicrobial agents and has the patterned diamond-like texture of shark skin.
